Network Hang

I have Network around 40 pc and i have window server 2003 server system and other systems windows xp and window vista and windows 7 also I have D-LInk DES1024D Switch but some times it hang then i power then open it will be ok after sometimes again problem 1 day 2 times it will be problem and i purchase new switch same model and replace again same problem so what was the wrong

My immediate thought after reading your post is that it may be the switch. Since you just bought the second one, take it back and exchange it for another make/model and see if you don't get better results with a different brand.
